DETAILED DESCRIPTION

As will be described below, embodiments of the present disclosure provide for dynamic, controlled, and context specific sharing of a user profile associated with a user device, and a destination device, based on the location of the user device and a destination location.

Referring now to FIG. 1, according to an exemplary embodiment of the present disclosure, a system for dynamically sharing a user profile of a device may include a user device 104. The user device 104 may be a computer device such as, without limitation: a smart phone, cellular phone, laptop computer, tablet computer, a computer system of a vehicle, or a device described below in connection with FIG. 4.

The user device 104 may include a user profile 250 and a program 202, embodied on a tangible storage medium thereof, as described in greater detail below.

Referring now to FIGS. 1 and 2, the user device 104 (FIG. 1) may include a digital user profile 250 (FIGS. 1 and 2) associated with the user device 104. The user profile 250 may include data associated with the user device 104 and/or with a user or operator of the user device 104. The association may be implemented using, for example, metadata of the user profile 250 that indicates an ID of the user device 104. The user profile 250 associated with the user device 104 may be organized as a record having discrete pieces of information. These may include, in one embodiment, name, age, car insurance policy number, health insurance information, etc., associated with the operator of the user device 104.

With continued reference to FIGS. 1 and 2, the user profile 250 (FIG. 1) and the information it contains may be a collection of constituent user profiles 210 (FIG. 2) based on combinations of these discrete pieces of information. Which of these combinations are used to form a constituent user profile may be determined dynamically, for example, by the operator of the user device 104 (FIG. 1). Alternatively, each of the constituent user profiles 210 may include a distinct copy of the information it references. For example, each of two constituent user profiles 210 may have a distinct copy of a “name” record.

Referring now to FIG. 1, the user profile 250 and/or its constituent user profiles 210 (FIG. 2) may also be associated with one or more destination locations 108. The association may be implemented using, for example, metadata of the user profile 250 that includes an ID of a given destination location 108. Destination locations 108 are described in greater detail, below.

The user profile 250 and/or its constituent user profiles may also be associated with one or more destination devices 116. The association may be implemented using, for example, metadata of the user profile 250 that indicates an ID of the destination device(s) 116. The destination devices 116 are described in greater detail, below.

Information stored as part of the user profile 250, associated with the user device 104, may be stored locally on the user device 104, for example, on a tangible storage medium of the user device 104. Alternatively, the user profile 250 may be stored on a tangible storage medium that is part of a Cloud system 220, described in greater detail, below. The user profile 250 may also be stored on both the user device 104 and on the Cloud system 220 as distinct versions, and each version may be synchronized with the other, according to any synchronization policy known in the art.

With continued reference to FIGS. 1 and 2, according to an aspect of the present disclosure, the user profile 250 may include, for example, the following constituent profiles:

-   -   A Restaurant Profile 210A (FIG. 2) comprising information         related to a restaurant patron and the patron's visit to and use         of dining services at a restaurant. The patron may be, for         example, an operator of the user device 104 (FIG. 1). The         Restaurant Profile 210A may, in one embodiment, contain the         following information associated with the user device 104 and/or         the patron: name, phone number, number of people typically in         the patron's party when dining at a restaurant (for example, at         the Restaurant Location 108A), the patron's allergies, and the         user's billing information. It may further include seating         preferences, preferred menu items, and additional information.     -   A Hospital Profile 210B (FIG. 2) comprising information related         to a hospital patient and the patient's visit(s) to and receipt         of healthcare services at a hospital. The patient may be, for         example, an operator of the user device 104. The Hospital         Profile 210B may, in one embodiment, contain the following         information associated with the user device 104 and/or the         patient, including: name, phone number, address, medical history         including allergies, and insurance information. Such information         may include Electronic Medical Records (EMRs). Although the         Hospital Profile 210B may share some information with another         profile, for example, the Restaurant Profile 210A, the user         device 104 maintains control over which user profile contains         what information, and thereby conveniently and automatically         regulates sharing of the information.     -   A Vehicle Rental Profile 210C (FIG. 2) comprising information         related to a vehicle renter and a visit by the renter to and use         of vehicle rental services at a vehicle rental facility. The         Vehicle Rental Profile 210C may include, in one example, the         following information associated with the renter and/or the user         device 104: Name, phone number, address, age, and insurance         information. Although the Vehicle Rental Profile 210C may share         information with other profiles associated with the user device         104, breaking down the information into individual user profiles         allows the user device 104 to regulate sharing of information.     -   A Retail Outlet Profile 210D (FIG. 2) comprising information         related to a shopper and a visit by the shopper to and use of         sales services at a retail outlet. The shopper may be, for         example, an operator of the user device 104. The Retail Outlet         Profile 210D may include, in one example, the following         information associated with the shopper and/or the user device         104: name, phone number, address, clothing measurements (e.g.,         shoe size, dress size, etc.), billing information, household         info, age, marital status, number of children, age of children,         number of vehicles owned, age of house, etc. Although the Retail         Outlet Profile 210D may share some information with other user         profiles associated with the user device 104, breaking down the         user profile 250 into individual user profiles allows for         dynamic and context-specific sharing of such information.

Referring again to FIG. 1, the user device 104 may be located at a user device location 106. The user device location 106 may be a geographic location of the user device 106, and it may be an absolute value, such as a pair of global positioning satellite (GPS) coordinates. Alternatively, the user device location 106 may be a relative value, such as “10 feet from a second location”.

The user device location 106 may be detected in many ways, including, for example, by a monitoring system, using global positioning satellite (GPS) systems, WIFI signals, Radio Frequency Identification (RFID) systems, or any other location tracking technology that can detect the presence of the user device 104.

With continued reference to FIG. 1, based on its user device location 106, the user device 104 may have a proximity 112 to a destination location 108. The destination location 108 may be a geographical location, and it may be a single value, such as a pair of GPS coordinates. The destination location 108 may be monitored and/or detected in many ways, including, for example, through GPS systems, WIFI signals, RFID systems, or any other location tracking technology that can detect the location of the destination location. According to an exemplary embodiment of the present disclosure, as depicted in FIG. 1, a destination location 108 may include: a Restaurant Location 108A, a Hospital Location 108B, a Vehicle Rental Location 108C, and a Retail Outlet Location 108D.

The user device 104 may have a proximity (not shown) to a destination device 116 where the destination device 116 is located at the destination location 108. This may be the case where, for example, the destination device 116 monitors and detects the proximity of the user device 104 to the location 116.

The destination device 116 may be a device similar to the user device 104, or a different device including, for example: a smart phone, tablet computer, desktop computer, or other electronic device as described in connection with FIG. 4, below.

The destination device 116 may be located at the destination location 108, or it may be located at a different location. In either case, the destination device 116 may be associated with the destination location 108. The association may be, for example, by way of an ID of the destination location 108 being included as metadata stored on a tangible storage medium of the destination device 116, and or a storage medium of the user device 104, or both.

The destination device 116 may be associated with the user profile 250, or a constituent profile 210 (FIG. 2). The association may be by way of metadata of the user profile 250 or a constituent profile 210 indicating an ID of the destination device 116.

The location of the destination device 116 may be detected in many ways, including, for example, through GPS systems, WIFI signals, RFID systems, or any other location tracking technology that can detect the location of the destination device 116.

In exemplary embodiments of the present disclosure, the destination device 116A may be a reservation computer or computer system of a restaurant at the Restaurant Location 108A, a hospital patient intake system 116B at the Hospital Location 108B, a client reservation system 116C at the Vehicle Rental Location 108B, or a customer service device 116D at the Retail Outlet Location 108D. The destination device 116 need not be located at the second location. For example, in the case of a restaurant that is geographically located at the Restaurant Location 108A, the destination device may be geographically located at a different location.

According to an exemplary embodiment, the user profile 250 information to which the destination device 116 gains access through the program 202, described below, may be used by the destination device 116 (and/or an operator of the destination device 116) to provide information, goods, and/or services to the user device 104 (and/or to the operator of the user device 104). In the example of a restaurant at the Restaurant Location 108A, the program 202 may provide access to the Restaurant Profile 210A to the destination device 116A. The destination device 106A may obtain information stored as part the Restaurant Profile 210A, such as credit card information, number of seats requested, etc. The information obtained from the Restaurant Profile 210A may be displayed to a user of the destination device 116A (e.g., an employee of the restaurant) or may be used by the destination device 116A to take corresponding action. The corresponding action may be, in this example, reserving a number of seats in the restaurant's reservation system, where the number of seats is equal to the number of seats requested as indicated in the Restaurant Profile 210A.

The user device 104 may have a proximity 112 to the destination location 108, and/or to the destination device 116 at the destination location 108. The proximity 112 may be a geographical proximity, or a temporal proximity based on the geographical proximity. The proximity may be a single value or may be a range of values, such as one or more latitude and longitude coordinates. The proximity may also be relative value, such as “10 feet away from” a given location.

The proximity value may be associated with one or more destination locations 116, and may be defined differently for each of the destination locations 116 with which the proximity 112 value is associated. A proximity 112 value may be associated with a particular destination device 116, destination location 108, and/or a user profile 250 or a part thereof. The proximity 112 may be defined by the user device 104 (e.g., through an operator of the user device 104).

An example of a temporal proximity value of the user device 104 may include: 10 minutes from destination location 108. This temporal proximity may be determined, for example, by calculating an average time required to reach the second location from GPS coordinates of the user device 104 at the user device location 106 when travelling 60 miles per hour.

Illustrative examples of the proximity of the user device 104 to a destination location, as depicted in FIG. 1, include: a proximity 112A to the Restaurant Location 108A, a proximity 112B to the Hospital Location 108B, a proximity 112C to the Vehicle Rental Location 108B, and a proximity 112D to a Retail Outlet Location 108D.

The user device 104 and the destination device 116, which may be located at the destination location 108 (for example, at the Restaurant Location 108A) or at a different location, may communicate via a Cloud system 220, which may include, for example, a server operatively connected to the user device 104 and to the destination device through a network. The network may include, without limitation, an internet network and/or a cellular network. Additional embodiments are discussed in greater detail in connection with FIGS. 4-7, below.

In another embodiment (not shown), the user device 104 and the destination device may communicate directly without going through a server or the Cloud system 220, using, for example, a Bluetooth protocol.

Each of the user device 104 and the destination device(s) 116, as well as the user device location 106 and the destination location(s) 108, may be monitored, tracked, or detected by a monitoring system (not shown). The monitoring device/system may include one or more monitoring devices (not shown). In one embodiment, the monitoring devices of the monitoring system may be integrated into the user device 104 and/or the destination device(s) 116. The monitoring system may be the same as, or a part of, the Cloud system 220.

According to an exemplary embodiment, the monitoring system may be a cellular network, and the user device 104 may be a smart phone. The destination device 116 may register an ID of the user device 104 with the cellular network, such that each time the user device 104 is detected by the cellular network as being within a geographic proximity of a destination location 108, the destination device 116 receives a notification (e.g., by text message) that informs the destination device 116 of the user device's 104 location.

In a related embodiment, the monitoring system may be the destination device 116, wherein the destination device 116 is capable of detecting the user device 104. In one example, detection of the user device 104 by the destination device 116 may be by way of using a Bluetooth protocol.

It will be apparent to one of ordinary skill in the art that other tracking, and monitoring systems may be used without departing from the spirit or scope of the present disclosure.

One or both of the user device 104 and/or the Cloud system 220 may also include a program 202 that provides functionality for granting access, to the profile 250 or a constituent profile (e.g., a profile 210 depicted in FIG. 2) associated with the user device 104, to one or more of the destination devices 116. Accordingly, the destination device 116 may access the user profile 250 or a constituent profile 210, when access to that profile is granted by the program 202.

The program 202 may also terminate the access, to the user profile 250, to the destination device 116, as described below in connection with FIG. 3.

The program 202 may detect, in step 304, that the user device 104 at the user device location 106 is within a proximity 112 (FIG. 1) of a destination location 108 (FIG. 1), which may be a geographic location of the destination device, or another geographic location. The detection by the program 202 may include, for example, receiving an indication from a monitoring system, as described above, indicating that the user device 104 is with the proximity 112 of the destination location 108. The destination location 108 may be, for example, the Restaurant Location 108A. The proximity 112 may be, for example, the proximity 112A. The user device location 106 and the destination location 116 may be the same location, for example, where the user device 104 is at the destination location 116.

The program 202 may, in step 308, provide access to a first user profile, associated with the user device 104, to a second device. The first user profile may be, for example, the user profile 250 associated with the user device 104, or a subset of the user profile 250, such as the Restaurant Profile 210A. The second device may be, for example, a destination device 116. The destination device 116, as described above, may be a computer at the destination location 108, or a computer associated with the destination location 108. The program 202 may identify the destination device 116 and determine if it is associated with any profile 210 (FIG. 2) in the user profile 250. For example, the program 202 may determine whether the destination device 116A at the Restaurant Location 108A is associated with a corresponding profile 210 in the user profile 250. Upon determining that such a profile association exists, the program 202 may provide access to the identified profile 210 by the destination device.

The program 202 may be a computer program embodied on a tangible storage device of the user device 104, or of a device that is part of the Cloud system 220, or both.

In a related embodiment, the program 202 may be, for example, a web service available to the destination device 116 and/or a program thereon. The destination device 116 may access the web service by providing identifying information of the user device 104 to the Cloud system 220 upon detecting the user device 104. The destination device 116 may query user profile 250 information associated with the user device 104 (or a constituent profile, such as those depicted in FIG. 2) using an expiring token provided to the destination device via the web service.

Referring now to FIGS. 1 and 3, according to an exemplary embodiment of the present disclosure, the program 202 (FIG. 1) may reside on a tangible storage medium on a first device, such as the user device 104 (FIG. 1) or on the Cloud system 220 (FIG. 1). In a related embodiment, the functionality of the program 202 may be distributed and/or duplicated among the user device 104 and the Cloud system 220, and/or a second device, such as the destination device(s) 116, in communication with the user device 104 and/or with the Cloud system 220.

The program 202 may limit access to the user profile 250 or a part thereof by the destination device. Accordingly, in step 312, the program 202 may generate an expiring token and associate the expiring token with the profile 210 (FIG. 2) to which access is granted in step 308. This profile 210 may be, for example, the Restaurant Profile 210A. The expiring token may be associated with the profile 210 to which access is provided, in step 316. The expiring token may be an electronic artifact or object with a unique ID. In each instance where the destination device 116 attempts to access the user profile 250 (or a constituent profile thereof), the program 202 may require that the destination device 116 provide the unique ID of the expiring token. The program 202 may grant access to the user profile 250 (or a constituent part thereof) where the unique ID matches a required unique ID, and where the expiring token has not expired.

The expiring token may be transmitted to the destination device 116 by the program 202. The destination device 116 may use the expiring token to access the user profile 250 (or a part thereof to which the destination device has access) with which the token is associated, on the user device 104 or on the Cloud system 220, where the user profile 250 is stored. The user device 104 may be pre-configured such that a user of the user device 104 is prompted to allow generation of the expiring token upon detecting that the user device 104 is within the geographic proximity to the location in question. This may be accomplished using, for example, a user interface displayed to the user of the user device 104 via the program 202 or via another program.

The token may expire according to a token expiration policy of the program 202. The token expiration policy may be defined dynamically. For example, the token may be set to expire upon the user device 104 leaving the geographic area wherein the presence of the user device 104 first triggers execution of the program 202, or upon the proximity of the user device location 106 of the user device 104 from the second location exceeding a threshold value. This may be, for example, upon the user device 104 leaving the Restaurant Location 108A (e.g. a user of the user device 104 leaves the restaurant while carrying the user device 104), the Hospital 108B, or the Vehicle Rental Location 108B. In a related embodiment, the expiring token may include a timer and be set to expire (t) minutes after it is generated. The duration (t) may be dynamically set by the user device 104 during runtime of the program 202. The token expiration policy may also be defined by a user dynamically during runtime, and the user may opt to select expiration by time, location change, or both. Accordingly, upon generation, the timer of the expiring token may begin a countdown to zero, and may expire upon reaching zero. A user of the user device 104 may manually cause the token to expire. Other token exchange and expiration policies are possible.

Depending on the token expiration policy used, as described above, the program 202 may terminate access to the user profile 250 (or to a portion thereof to which access was provided) by the destination device, in step 320, such that the user profile 250 is no longer accessible by the destination device. Additional safeguards may be implemented to ensure that the information is not retained by the destination device.

In other steps (not shown), the program 202 may receive information via the user device 104, the destination device, and/or the Cloud system 220, to update the user profile 250. Such information may correspond to, for example, an experience of a user of the user device 104 while at a location such as the Restaurant Location 108A. For example, the user of the user device 104 may have a new dining preference and may indicate this new dining preference to a user of the destination device, such as an employee of the restaurant at the Restaurant Location 108A. The user of the destination device may input the new dining preference directly or indirectly to the destination device. The destination device may communicate the new dining preference to the program 202 via the Cloud system 220 or directly to the user device 104. In a related embodiment, the new dining preference may be input into the user device 104. Updating information associated with a shared user profile need not be by way of user input. It may be done automatically. For example, if the destination device detects that a new credit card is used to pay for a meal at the Restaurant Location 108A, the new credit card information may automatically be transmitted by the destination device to the user device 104 and/or the Cloud system 220, through, for example, the program 202.

Irrespective of the manner of detection and/or input and which device receives and/or communicates the input, the corresponding information may be used by the program 202 to update the user profile 250 or a constituent profile 210 (FIG. 2) thereof.

Access to the user profile 250 by the destination device for the purpose of updating the user profile 250 may be limited in the same manner as access to retrieve information from the user profile 250 is limited. In other words, while the expiring token is not expired and access is not terminated, the user profile 250 may be updated. Where an update to the user profile 250 is initiated by or via the destination device, the program 202 may tentatively process the update subject to an affirmative approval indicated by or via the user device 104 (for example, upon the user's approval indicated through an input to the user device 104).

Non-limiting benefits of embodiments of the present disclosure include allowing the automated exchange of information between the user device 104, which may be operated by a user, and a destination device, which may be operated by a second user, such as a business or service provider that permits the business to provide a customized experience to the user in an efficient manner. This allows the user device 104 to share information seamlessly via the but discretely, so that only information that is associated with the destination device or the second location is shared. The user of the user device 104 need not specify which information to share each time the user visits the second location, because the information shared is context specific. The user device 104 and/or the user can decide what information is shared in a given context. Accordingly, the destination device and/or a user of the destination device will only have access to the user profile information of the user device 104 temporarily. Not only does this allow the user device 104 information to be shared selectively depending on context, it also allows the destination device to access and use information that is current and most useful, rather than storing information that my be stale.

Although discussions of the various embodiments of the present disclosure have involved using these embodiments for the purpose of maintaining confidentiality, such purpose does not limit the spirit or scope of the present disclosure, and other uses are expressly contemplated.

Furthermore, although discussions of some of the embodiments above have included one or more users, the functions described may be performed automatically and do not require manual input, and may be performed in an entirely automated manner.
